When you see a red saving, best is to stop editing your app and waiting for the thing to get back to normal before making more changes. If a connection issue happens, we can’t really do anything to recover the changes.
Is it still happening? If yes, please file s big report and we’ll check.
I have the same problem sadly. Stuck on ‘Saving…’.
I tried a commit hoping that when my changes are gone the commit will have picked them up - but I guess that’s just wishful thinking…
